To all whom 'it may commi: l

Be it' known'that we, HARRY O. BIsniNo and WILLIAM L. SooY, citizens of the United States, and res-idents of Coshocton, in 'the county of'CQshocton and State of Ohio, have' invented a new and Improved Apparatus for Molding Bottles, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a machine of "the character set forth With a revoluble molding table having a series of molds thereon; to provide a reciprocating head having mo'unted thereon a blowing pipe and a parting moldfor shaping the necks of bottles; to provide means for elevating and depressing said reciprocating head;and to provide a machine the construction .of which is simple, economical 'and'durable One embodiment of the present invention. is disclosed in the structure illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts in all the views, and in which--A Figure 1 is a front elevation of a machine constructed and arranged i'n accordance with the present invention; Fig. 2 is a vertical section taken on the line 2--2 in Fig. 3; Fig. 3 is.a horizontal section taken on the line 3-3 in Fig. 2;. Fig. 4 is a' detail view, on an-enlarged scale, of the'bottle body mold; Fig.

5 Iis a Idetail view, fragmentary i'n form,

showing in sectionthe body mold, neck mold and reciprocating head in operative` positioniand Fig. 6 is a similar view showing the bottle as completed in themolds, the neck mold as removed and th'e reciprocating head as partly lifted.- .t

The supporting table lllisfsuitably mountedupon legs 12. 12, and is provided with -a central pedestal'l.' The pedestal-,13 is pro vided at theupper end'with an annular flange 14 which serves the double purpose of sup- 'portingthe molding table'in sliding rela-. tion and for holding the 'elevatorfc'1"ane`forl the reciprocating ,heady Disposed at'pthe' outer edge of thetablell, and vertically'ex-l tended thereon, are lugs 15, 15.` The lugs 15,

15-are suitably tap ed to receive the lscrew threaded sectionso -bolts:16', 16, The bolts 16, 1-'6 Ihave a bearing section upon fwhich. ,are rotatively mounted'supporting"rollers 17 ,'17 The 'rollers 17, 417- serve .to support the outer edge of aA molding table'lS, a depending a track' for" the operationn of the said table.

The molding table 18 is provided with'a plurality of bottle body molds .preferably blank molds in which'the neck oil the body is body of the' bottle is Shaped by being blow-n 'to conform to the said molds. The blank molds comprise Aasolid cylindrical body portion 20, having extended therefrom a series of radiating ns 2l, 21. Each mold is held 4stationarily.upon the table 18 by the finsv ..21 resting 4upon' the top of the said table, and by a ring 22 which is set within angular re'- ces'ses for-med Yinthe ,said fins, which rin is fixedly mounted in anopenjng- 23 forme in ings 23 are cross bars 24; having-apex" oration 20. The perforation formed in the vbar .24 1s to' provide a gnide for a! piston rod 25.

ton head forms thebottom of the body porthe molten glass when" the same is delivered thereto. The body molds forming the second 'series are two-partinolds, and are pivotally portions 28 of the said molds are provided to receive: the pins' 27, and to. hold the body Aportions 28, and -to form a, radius for the swing of the said body portion` parts lof themolds on, arcs, the curves of which are substantially diametric' to the inner cylinder 'of the body portion 28..' The 30,' 3Q`arranged,-as shown in Fig.' 3 ofthe said molds is provided 'witha piston,`-the -bythe numerals '26 and 'the pistonsiof'he 31,131., The upper face of. each or thefpistons .26"s hollow,'s'ubstantially `as shown in Fig. 2 bf the drawings," to assist inthe' function pe'rfmed'by the said piston of lifting the flange 19 being provided to forniva surface which may be machined accuratelyV to form arranged in tvvo series, one series comprising.

tion formed therein' concentric'with the open mg 23 and' with the center of the body por-'f `The piston rod'25 is rigidly or integrally' connected with a piston head-26, which' pis to provide for the opening of thetwo-I y moltenfgliissto top of the' body portion formed, .and the body molds wherein the the table 1s. Extended across alegan 0' eiltion 20 andforms therewith a; receptacle for i mounted'upon pivot pins 27, 27. bodywith elongated'hinge arms 29, 29 provided drawings,so that Athe mold `sections may be parted-as land when desired., Each ,'f'th'e` 'pistons ofthe 4blanlrnmlds beingindicated body moids'peing indicated by -une nemers-'isi 20, The pistons 31 are shaped-at the top surface to the t'orin desired for the bottom or the bottle. llaeh ot the pistons is provided with a pist on rod, the piston rods of the pi tons Qt? being indicated by the nu1neral'25 and thc pistonrods of the pistons 3l being indieated bv the numeral Disposed in the path of the piston rods and 32 is a plunger 33 guidably mounted in a perforation formed in the ltable l1 and in a boss 3l depended from the under surface thereof. The plunger 33 is lixedly connected b v means of a link 35 with a lever 3G. The lever 3o is pivotallyA mounted at 37 upon a bracket 38 extended tronrthe under Side and bolted to the table ll. The lever 36 is provided with a hand hold 3f) whereby the said lever is pumped b vthe operator to raise and lower the Said plunger 33.

A cross head 40 is adjustably mounted in tixed relation upon a guide rod 4l. to which it is, securedrby a holt-42. The guide rod 4l is tubular in form ,and open-ended to provide a'passage 'for a cable'43. The rod 4l is slidahly mounted in per-forations formed in l'iracltets 44j, Yi4 extended from the side of an elevator erane 45. The said rod .is non rotatively held in the brackets 44 by means ot' a feather 46 suit'al'ily mounted in grooves provided in the said brackets and said har. The crane is priivided with a cylindrical foot 47 which is trued to form a pivot on which the tahle 13 rotates. The foot 47 i (E3 and (14 arc shaped to produce an inner ot' the crane 45 is rigidly mounted on the;

pedestal 13 and the tlauge lllthereot hyl being holted thereto by holte 43, 43. The cable 43 is secured hy an e'velet fl-fl to a 'oot lever 5t). rl`he foot lever 50 I'iivotally1 mounted at 5l in one of the legs l2. The cable 43 is reeved over sheaves i. supported in the end of the crane 45, and is then anchored to an eyelet 53 pivotally mounted in the cross head 4t). llt by means of the eahle 43 and lever-5t) that the eross head l0 is elevated and lowered. f

Upon the cross head 'lf) is carried a blow pipe 3l and a con'ipreesed air pipe designed ior. blowingI the bottle. hotly when the glass is held within the body molds Q3. The. blow pipe 54% is guided hy a block :16, the lower end whereof is projected to form the core 'for Slraping the neelr passage of the bottle, rthe upper end'of the pipe :3l-is rigidi)Y connected with a connecting; hloeli' 5T. which bloeit is provided with an annular pasfla :3o. 'the one end whereof opens into a nipple fr.) to which is coupled the pipe t lnt't'ddinff the pipe a Spiral Spring UJI (3o. t ne ends .whereof rest upon the eroea head E en) and die bloeitA 5T and over-ate'normallv ,.t t v to support the d block at above the erosie head lit). ",lfo li t the litt of the block 577 set holt tl. la provided in a standard 62,

i., It and 6 of the draw mounted upon the erosie head molding surface adapted to forni the outer surface ot the neck, and to form, 1n conpincn tion with the. hloclt 56, a completed neck forA the bottle. The said mold see-tions are provided with hinge arms o5 and 66, the ends whereolg are perforated to be rotativel)y mounted upon a pivot bolt (37. rl"he pivot holt (5T is provided with a Screw threaded end section "3S to engage in holding relation the rross head 4t). and with an extended flat head tft to rest under and support'. the said mold sections o3 and (34. The said mold .sections are opened and closed in clamping relation upon the block 5G, and for this purpose they are provided with handles 705 70.

The table 13 is preferably rotated hy hand, and tor thisI purpose there is provided a .series ol" spokes 7l, Tl. laterally extended 'from the periphery of the said table. For the purpose ot alining the table so that the molds above .lescrihed will register with the cross head 4t), the table is provided with a series of lugs 72./ Separated to form Slots to receive. the detcnt head of a locking lever 73. rl`he locking lever T3 is mounted on a standard 74 extended 'from the table l'l, shown particularly in Fig. l of the drawings. The.

head ot' the lever T3' is held upward against the table 18 by means ot' a spiral spring 75, suitably disposed to accomplish this purpose. When now the table 13 rotated,v it is automatically arrested at each ot' the registering stations where the molds and Q3 aline with the cross head at() and the noch' mold sections (33 and ttl mounted thereon.

lit is to provide 'for cooling the sections U3 and G4. that each is provided with a semicircular passage 7th which is supplied with cooled water throu'l'i a pipe 7T. A similar pipe to carry ott' the water as heated is 'extended t'rom the olmos-ite end ot' the said pasnage Tt. ln this manner the sections G3 and ttt are maintained in 'condition to chill f the glass l'oruiine the ncclt ol the bottle. This is essential, as in the operation the neel( thus formed provides a supporting*strut:- tiire for 'the glass while beingA transferred from the blank molde or body portion 2t) thereof to the bodylforining molds or body'- as iol poured port ton vsections (3?) and (34 released to allow the cross head 40 to descend above the mold 20. The neck mold sections G3 and (34 are drawn together by the handles 70 upon the block 5G. The said sections 6 and (34 and block 5G thus arranged fit snugly upon the body portion 2() and form a perfeet' closure therefor. In this position the lever 36 and the plunger 33 carried thereby are lifted to raise the piston 26 until the glass flows around the core end of the block 5G and into the mold formed by the sections 63 and 64. lVhile in this position the pipe 54 is depressed to form a passage B in the glass A of the body portion of the said glass. The contact of the hot glass with the cooled quickly congeals the glass comprising the neck of the completed bottle.

The lever-30 is now depressed, lifting, byl

means of the cable 43, the cross head 40, and -carrying upward therefrom the hot glass A. The table 1S is quickly rotated un-til the body mold is alined with the cross head 40. The body mold is in spread position,-and in this position the' lever 50 is released to allow the cross head to sink to its proper level, when 4the body of glass A will be in position above the piston 3l. In this position the sections forming the body mold 28 are closed, the handles 30, lll'being used therefor to sur- -round the said glass A. It will, be noticed by reference to the drawings that the inner diameters of the body portion 20am] the body portion vary, the former being considerably smaller. This insures the glass from which the body of the bottles is to be formed from being crowded or chilled by contact with the sides of the mold 2H. ln this position, the neck molds being still in holding relation upon the neck of the bottle7 the cock 7S is turned to open the passage from the nipple 5S) to the pipe 54.' The compressed air is tlms introduced into the passage l formed in the glass body A, and the blowing of the body of the bottle is augmented. As the body of the bottle is gradugally expanded to lill the mold 28, the pipe 5ft is gradually loWeref-hthe nose of the said pipe being maintained free to contactI with the molten glass. During the operation, if it be desired, the piston '31 is raised by means of the lever 36 so that the mold. for

y. the bottom of the completed bottle is more firmly impressed thereon.

At the end of the operation it will be found that a completed bottle, having a molded neck of exact' dimensions, will be formed, having a blown body, andthe outer `same rotary path, said molds being alternately disposed; a two-part neck mold disposed in the path of said body molds and above the same, said neck mold being arranged to register with said body molds; ay reciprocating mechanism for raising and lowering said n eck mold to close each of said body molds; an air blowing mechanism embodying ablow pipe carried by said recip rocating mechanism; a liftingl bottom for each of said molds; and an elevating mechL anism for lifting the plastic glass into said neck mold.

An apparatiis for molding bottles, eom- I'irising a rotary tabl'e having a series of openings; a supporting table for said Irotary table having a series of carrying Wheels pivotally` mounted thereon and upwardly extend-ed to support said rotary table; a blank mold having a solid body and .radiating tins extended from the sides ot saidvbody and resting over said openings; a body mold embodying two halt' hinged sections provided with handles for maniI/)ulating the said sections; a plurality of disks slidably mounted on said table to move perpendicularly therein, said disks adapted to form the bottoms ot said molds; a two-partneck mold disposed in the path ol said body mold and above the same, said neck mold being a1'- ranged to register with said body mold; a reciprocating mechanism for raising and lowering said neck mold to close said body an air blowing mechanismembodying a blow pipe carried by said reciprocating mechanism.

ln testimony whereof we have signed this specification in the presence of two subscribing witnesses.
